Filed: 1980-07-28
Abstract: PURPOSE:To obtain a ring trip circuit possible for circuit integration by utilizing a current Miller circuit, differential amplifier, and gate circuit. CONSTITUTION:When a telephone set 10 is at on-hook, a voltage waveform of points A and C is changed in AC manner. When a voltage waveform at the point A is positive, a transistor TR17 of a current detection circuit 14 is operated and the voltage is converted to a voltage in VB at a differential amplifier 21. When negative, a TR16 is operated and also the voltage is converted into voltage VB. This output is converted into a pulse with a TR29. At the telephone set 10 in off-hook, since a DC current flows, the output waveform VB of the differential amplifier 21 operates by taking a voltage increased by a DC voltage E3 as a center. This output is pulse-converted at the TR29. When the product between this pulse and the gate pulse (produced when a signal of an AC signal generator 36 crosses with a symmetrical line) is taken at a gate circuit 27, a pulse is obtained at Vout only ay on-hook.
